長斑就(jiu)是(shi)一個很令(ling)人煩惱的問題,大部分都是(shi)長(chang)在面部較(jiao)多,比(bi)較(jiao)顯眼的位置。長(chang)在臉上也十分影響心情,甚至會遇(yu)到交際問題。
斑也分為定性斑和活性斑:
活性(xing)斑(ban)(ban)(ban)(ban)(ban):黃褐斑(ban)(ban)(ban)(ban)(ban)、角化斑(ban)(ban)(ban)(ban)(ban)、額頭斑(ban)(ban)(ban)(ban)(ban)、腎恐斑(ban)(ban)(ban)(ban)(ban)、肝(gan)斑(ban)(ban)(ban)(ban)(ban)、脾(pi)斑(ban)(ban)(ban)(ban)(ban)、眼周斑(ban)(ban)(ban)(ban)(ban)、蝴蝶斑(ban)(ban)(ban)(ban)(ban)、反彈斑(ban)(ban)(ban)(ban)(ban)、曬(shai)斑(ban)(ban)(ban)(ban)(ban)、唇上(shang)斑(ban)(ban)(ban)(ban)(ban)、妊(ren)娠斑(ban)(ban)(ban)(ban)(ban)、激素斑(ban)(ban)(ban)(ban)(ban)、膽斑(ban)(ban)(ban)(ban)(ban)。
定(ding)性斑(ban):雀斑(ban)、老年斑(ban)、真皮斑(ban)、點(dian)狀黃褐斑(ban)。
黑色素的(de)含量也是皮(pi)(pi)膚(fu)(fu)(fu)顏色的(de)主要(yao)因素,也就(jiu)意味著斑的(de)顏色深(shen)淺(qian)也是尤其(qi)決定的(de)。此外,膚(fu)(fu)(fu)色還受皮(pi)(pi)膚(fu)(fu)(fu)表(biao)皮(pi)(pi)角質層(ceng)的(de)厚(hou)(hou)薄、表(biao)皮(pi)(pi)透明層(ceng)及顆粒層(ceng)的(de)厚(hou)(hou)薄影(ying)響(xiang)。若角質層(ceng)較厚(hou)(hou),則皮(pi)(pi)膚(fu)(fu)(fu)偏黃色;顆粒層(ceng)和透明層(ceng)厚(hou)(hou),皮(pi)(pi)膚(fu)(fu)(fu)則顯白(bai)色。
據目前臨(lin)床研(yan)究發現(xian),日曬、日光是對黑(hei)素(su)代謝影響最大的(de)(de)外部因(yin)素(su),紫外線可使(shi)表(biao)皮內的(de)(de)黑(hei)素(su)小體迅速重新分布,將黑(hei)素(su)集中到日曬部位(wei)。
研究發現,神(shen)經(jing)因(yin)素同樣(yang)會影響(xiang)黑素代謝,長期處于精(jing)神(shen)緊張、疲勞甚至是(shi)失眠的(de)狀況,將影響(xiang)人體的(de)神(shen)經(jing)功能及腎上腺皮脂功能,激發斑的(de)形成。
